The official Bing app only dropped in December, but the Bing blog reports that a new and improved app is now available for free from the App Store. Some new features include the incorporation of bookmarks, copy and pasting URLs, and direct sharing via e-mail, along with a host of other new features and tweaks.

Of course, there are rumors swirling around that Bing might be coming to your iPhone in other capacities than an official app, which, with the Apple-Google continuing to escalate, don't seem so far fetched. [Bing]
